Schorr and his team recorded 1,100 deep-dives, averaging 0.87 miles deep, and 5,600 shallow-dives, averaging about 0.17 miles deep. The longest dive lasted an amazing 137 minutes.
Southern elephant seals set the prior record. Their dives have been measured as being up to 1.5 miles deep and lasting 120 minutes.

As of now, the Cuvier's beaked whale record is untouchable, and their skill even goes beyond the mentioned records.
Both deep-diving elephant seals and sperm whales require an extended recovery period after long, deep dives. Not so for Cuvier's beaked whales. They average less than two minutes at the surface between dives.
Unfortunately, the species accounts for 69 percent of recorded marine mammal strandings associated with military sonar operations.
Peter Tyack of the Woods Hole Oceanographic Institution has also studied Cuvier's beaked whales. He said that the normal deep diving behavior of the whales does not pose a decompression risk.
